CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application Ser. No. 62/312,275 filed on Mar. 23, 2016, entitled “Devices and Tools for Improved Hunting,” which is incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to hunting mechanisms, and more particularly to a quick-detachable multi-purpose accessory mounting platform.

BACKGROUND

Various devices and tools are used in connection with hunting; however, as described herein, these devices and tools have various drawbacks that hinder the hunting experience and results thereof. Examples of some of the drawbacks of each device and tool are separately described.

Autonomous Trap Magazine

Shotgun shooters routinely utilize clay target throwing devices to hone skills necessary to hit moving targets while the targets are in flight. A variety of clay target throwing devices are available to the consumer ranging from hand-operated manual throwers to electrically driven autonomous traps which can launch multiple clay targets simultaneously. Lightweight, portable autonomous traps allow a single shooter the convenience of clay target shooting unaided by a helper, and this style of trap can be easily set-up quickly in the field to mimic specific shooting scenarios. Autonomy is aided by a remotely-located, push-button switch which, when pressed, cycles the trap to launch the clay target. A universal feature of autonomous traps is the hopper in which multiple clay targets are simultaneously stacked prior to the onset of the shooting session. Each clay target in the stack is gravity fed into the trap separately and automatically, eliminating the need for the shooter to repeatedly reload the trap between shots and also freeing the shooter from remaining in close proximity of the trap during a shooting session. In the case of portable autonomous traps, the hopper is typically disassembled for transportation and storage of the trap. At the shooting site, the hopper must be assembled and mounted onto the trap using hand tools prior to the trap's use. However, clay targets cannot be loaded into the hopper until the hopper is mounted on the trap.

Weathercocking Arrowhead

Broadhead arrowheads including several sharpened blades arranged circumferentially about an arrow tip may be utilized extensively in the dispatching of medium and large game with a hunting bow. In general, there are two types of broadhead arrowheads. The first type is a fixed-blade broadhead, incorporating blades that are rigidly attached to the tip of the arrow. The blades of the fixed-blade broadhead may be permanently attached to the arrow tip, or they may take the form of replaceable blade elements which can be individually replaced when damaged or dull. The main advantages of the fixed-blade broadhead are simplicity and reliability. The main disadvantage of the fixed-blade broadhead is that the maximum diameter of the blades must be kept relatively small in order to preserve flight characteristics that mimic an axisymmetric field point arrow tip that has no blades, which is widely utilized in archery practice and training exercises. The second type of broadhead is a mechanical broadhead, and it generally may include blades that are held in a closed, streamlined position close to the axis of the tip when the arrow is launched and while in flight. Upon impact, the blades rotate radially outward to increase the effective diameter of the broadhead during penetration and creation of the wound channel. The main advantage of a mechanical broadhead is that the maximum diameter of the expanded blades can be greatly increased over that of a fixed-blade broadhead without adversely affecting the flight of the arrow. However, this increased diameter comes at the expense of mechanical complexity and system reliability. To be effective, the mechanical broadhead must remain in the closed position during launch and flight, and must also expand symmetrically and completely during the penetration event.

An examination of the relevant aerodynamics of an arrow in flight follows. An arrow can be described with respect to three major components: the tip, the shaft, and the fletching. During flight, an arrow is subject to disturbances (for instance, when launched from a poorly tuned bow) which may cause the arrow to oscillate around its center-of-gravity (cg) located at a point on the shaft centerline centrally located between the tip and the fletching. The aerodynamic lifting and/or yawing force generated at the tip of the arrow causes a destabilizing overturning moment about the cg, while the aerodynamic force generated by the fletching counteracts this destabilizing moment by providing a larger, corrective stabilizing moment about the cg in opposition to that generated by the tip. The net sum of the stabilizing and destabilizing moments can be resolved into a single force located at the center of pressure (cp), also located on the axial centerline of the shaft. To achieve stable flight of the arrow, the cp must be located behind the cg. If the cp is located ahead of the cg, the destabilizing moment produced by the nose may be greater than the restoring moment produced due to the fletching. As such, it becomes clear why a conventional fixed-blade broadhead must be limited in blade diameter; the larger the blade diameter, the greater the destabilizing overturning moment will be, producing a consequent adverse effect on the flight of the arrow. In essence, any non-blunt aerodynamic tip shape that is rigidly attached to the arrow shaft will cause a destabilizing moment to occur. In relative terms of increasing destabilization, the axisymmetric field point will produce the least amount of destabilizing moment, followed by the mechanical broadhead in the closed position, followed then by the fixed-blade broadhead.

Smoothbore Shotgun Slug

Slugs designed to be fired from a smoothbore shotgun barrel are typically less accurate than slugs designed to be fired from a shotgun having a rifled bore. Several reasons exist for the inaccuracy of slugs fired from smoothbore barrels. One major reason for the inaccuracy is that the smoothbore slug typically lacks adequate static margin, which can be defined as: (Xcp−Xcg)/L*100%, where Xcg is the axial location of the center of gravity measured from the nose of the projectile, Xcp is the axial center-of-pressure also measured from the projectile's nose, and L is the axial length of the projectile. If the static margin is small or negative (for example, less than 5%), the projectile can easily be diverted from the intended shot line due to a lack of longitudinal stability. Small static margin values are inherent in slugs intended for a smoothbore shotgun barrel, as these slugs are low in aspect ratio and cylindrical in form, and this form does not accommodate means for shifting of the center of pressure rearward as required for increased stability. In addition to limited static margin, another major reason for the inherent inaccuracy of a slug fired from a smoothbore barrel is that no roll moment, or an inconsistent roll moment, is imparted to the slug. Induced rolling reduces impact dispersion by averaging out asymmetric forces imposed on slug during launch and while in flight.

To increase accuracy, many shotguns intended for sporting purposes originally fitted with a smoothbore barrel can be retrofitted with a rifled-bore barrel; however, the cost of the rifled-bore barrel can be of the same order as that of the original shotgun. Along with the cost, another downside to installing a rifled shotgun barrel is that the shotgun then becomes a special purpose firearm intended for use against medium to large game, thus limiting the type of game that can be pursued during an outing in the field. Even though smoothbore shotgun slugs are less accurate, they have the advantage that usually no alterations to the shotgun are necessary. This allows a shotgun having a smoothbore barrel to retain the flexibility of taking both small and large game merely by changing ammunition.

Quick-Detachable Multi-Purpose Accessory Mounting Platform

When hunting with a firearm, it is convenient to have accessories such as a flashlight, infrared spotlight, and/or a remote dog training transmitter easily at hand. This can be accomplished by mounting accessories on the firearm within easy reach of the shooter's non-trigger hand, and in an orientation that allows for immediate operation during the act of both carrying and shooting the gun. Furthermore, conditions such as weather, terrain, intended quarry, day/night or night/day transitions, etc. may change during a hunt. The ability to quickly attach or detach various accessories from the firearm, or to quickly attach or detach the entire mounting platform (with the accessories remaining attached to the platform) allows the hunter to better adapt to the changing conditions. Quick-detach firearm-mounted accessories are in common use for military-style firearms which routinely include features such as integrated Picatinny rails for that purpose. However, in contrast to military-style firearms, firearms intended for sporting use are typically not factory-equipped with mounting points for such accessories.

Glock Magazine Release Button Removal Tool

The as-issued magazine release button on a Glock pistol is often replaced, or in the case of left-handed shooters, reversed, to offer the shooter better operational characteristics when changing magazines. The button is usually operated by pressing inward with the thumb of the shooter's dominant hand, with the motion of the button being transverse to the line of fire. The standard button head on a Glock pistol is relatively small and mounted nearly flush with the frame surface such that operation of the button under stress or during extended training sessions can become difficult. Aftermarket replacement buttons typically offer increased button head surface area, and they may increase the operational travel via greater offset of the button head from the frame.

The release button is held in the frame by a vertically oriented, cantilevered, straight steel rod spring inset into a “V” shaped cavity located in the forward face of the pistol frame's magazine well. The fixed end of the spring is held captive by the cavity walls at the narrow end of the cavity near the bottom of the magazine well. The free end of the spring is located higher up in the magazine well where the wider end of the “V” shaped cavity allows room for the free end of the spring to travel side-to-side. The free end of the spring is contained within a slot in the magazine release button which has an opening near one end to allow the installation of the spring's free end into the slot. The free end of the spring elastically bends side-to-side to initially resist the motion of the release button when depressed, and to return the release button to its original position when released.

Removal of the free end of the spring from the slot in the magazine release button occurs to replace or reverse the release button. Flat-bladed screw drivers and dental picks are common impromptu tools which are used to manipulate the free end of the spring toward, and out of the open end of the slot. Access to the spring can only be had through the top or the bottom of the magazine well, which severely limits access to the spring, and causes poor purchase between the impromptu tool and the side of the spring. In many instances, damage to the polymer frame occurs when the impromptu tool slips away from the spring and strikes the edge of the molded spring cavity; the resultant burrs raised on the inside of the magazine well can adversely affect the release and retention of the magazine.

DETAILED DESCRIPTION

Autonomous Trap Magazine

Embodiments of the present disclosure may improve upon current hopper designs, in that the hopper may be transformed into a magazine, and once assembled, it may remain assembled indefinitely. Furthermore, embodiments of the present disclosure may allow the magazine to be pre-loaded with clay targets at any time prior to a shooting session, and also may allow for the loaded magazine to be installed on or removed from the trap quickly without the need for hand tools. Multiple loaded magazines according to embodiments of the present disclosure can be utilized in succession to drastically reduce downtime between shooting sessions as compared to refilling a conventional hopper.

FIG. 1 depicts a perspective view taken from the user's right side of portable autonomous clay target trap 400 according to the prior art. Trap 400 utilizes hopper 405 and top plate 410. FIG. 2A depicts a top down perspective detail view of the bottom of hopper 405 (FIG. 1), indicating a plurality of guide tubes 415 which insert individually over trap studs 420. The location of spring-loaded clay target holding block 425 is also shown. FIG. 2B depicts a top down perspective detail view of the top of the plurality of guide tubes 415 according to the prior art, to which top plate 410 is mounted using a plurality of screws 412.

FIG. 3 depicts a top down perspective view of magazine 418 created from hopper 405. The plurality of guide tubes 415 may be inserted into permanently mounted bottom plate 440. However, there may be embodiments of the present disclosure wherein bottom plate 440 may not be permanently mounted. Further, while a plurality of guide tubes 415 are depicted, it should be appreciated that one or more guide tubes 415 may be utilized without departing from the present disclosure. Temporary stop-blocks 435 may be installed on either side of one or more individual clay targets 430.

FIG. 4 depicts a top down perspective view of bottom plate 440 which may incorporate one or more integral raised supports 445. While supports 445 are described are integral, it should be appreciated that they may not be integral without departing from the present disclosure. Hole 450 may be placed into each support 445, which may accommodate set screw 452 that may tighten against one or more guide tubes 415 (FIG. 3).

FIG. 5 depicts a top view of bottom plate 440 which may include rearward offset through-cut 460 and forward offset through-cut 465. FIG. 6 depicts a bottom up perspective view of bottom plate 440, which may incorporate flat bottom 455. However, it should be appreciated that there may be embodiments where bottom 455 is not flat without departing from the present disclosure.

FIG. 7 depicts a top down perspective view of temporary stop-block 435 including one or more notches 470 which may press outwardly against one or more guide tubes 415 (FIG. 3) via tensioning slot 485. Travel stop 490 may limit movement of thumb button 475, while finger ring 480 may aid in the removal of stop-block 435 from one or more guide tubes 415 (FIG. 3). FIG. 8 depicts a top view showing an orientation of temporary stop-block 435 where one or more notches 470 may make contact with one or more guide tubes 415.

Operation according to embodiments of the present disclosure may be illustrated by evaluating the operation of hopper 405 (FIG. 1) from which magazine 418 may be derived. Typically a hopper may be inserted onto trap 400 by first individually installing one or more guide tubes 415 onto one or more trap studs 420. After one or more guide tubes 415 are installed on a trap, top plate 410 may be installed via screws 412 as shown in FIG. 2B, followed by inserting one or more clay targets 430 (FIG. 3) into an assembled hopper. In the past, this assembly process was required each time a trap is used. Embodiments of the present disclosure may convert the hopper into magazine 418 by the addition of bottom plate 440. In some embodiments, bottom plate 440 may be permanently attached which may allow top plate 410 to also be permanently attached. When magazine 418 has been assembled, it may then be fully loaded with one or more clay targets 430 which may be held in place by one or more stop-blocks 435 installed above and below the one or more clay targets. The magazine including one or more installed clay targets may then be placed on one or more trap studs 420 and the one or more stop-blocks can be removed.

Several design features of bottom plate 440 may aid in the utilization of the hopper as a removable magazine. For example, the horse-shoe open-ended shape of the bottom plate may allow for clay target holding block 425 to make contact with the edge of the lowest clay target and control the feeding of the clay targets into the trap. Further, bottom plate 440 may include aft cutout 460 (FIG. 5). This aft cutout may allow for clearance between the edge of the one or more clay targets and the bottom plate when the trap may be operated at various launch angles.

Weathercocking Arrowhead

Embodiments of the present disclosure may eliminate the destabilizing moment produced by a fixed-blade broadhead arrowhead by placing a rotational degree of freedom (a pivot joint) directly at the center of gravity of the broadhead arrowhead itself (cgah). In combination with the introduction of the pivot joint, an arrowhead according to embodiments of the present disclosure may be designed such that the center of pressure of the arrowhead itself may be located aft of the cgah position. When designed according to these conditions, the arrowhead may align itself with the relative wind (i.e., weathercock), and therefore not produce a destabilizing moment about the cg of the entire arrow. Thus, the restriction heretofore placed on the fixed-blade broadhead can be removed; namely, the broadhead arrowhead according to embodiments of the present disclosure can be of relatively large diameter without affecting flight performance. Further, if the bow is tuned properly so as to minimize launch disturbances, conventional fletching usually required on the arrow to offset the destabilizing moment generated by the nose tip may be reduced significantly or eliminated entirely.

FIG. 9 depicts a perspective view taken from the user's right side of weathercocking broadhead arrowhead 500 constructed in accordance with embodiments of the present disclosure. The forward end of the broadhead arrowhead may include nose tip 530 to which one or more broadhead cutting blades 540 may be rigidly attached. These broadhead blades can be permanently attached to the nose tip, or can be inserted into grooves in the nose tip and held in a fixed position such as through internally threaded blade-lock collar 580 which may mate with external threads (that may or may not be integral) located on the aft end of the nose tip. The broadhead arrowhead may be conventionally attached to tubular arrow shaft 510 by means of internally threaded insert 590. The aft end of each broadhead blade may contact alignment disk 520 which may be in sliding contact with the arrow shaft.

FIG. 10A depicts a front view of broadhead arrowhead 500, showing the relative circumferential positioning of one or more blades 540 about nose tip 530 and the axisymmetric geometry of alignment disk 520. The location of section view (FIG. 10B) is also indicated which may pass through the center of said nose tip. FIG. 10B depicts a left side cutaway view of a broadhead arrowhead, showing the aft externally threaded end of nose tip 530 to which internally threaded blade-lock collar 580 and internally threaded ball 560 may be mechanically attached. The ball may be held in position against socket 585 by means of internally threaded tube 570 whose forward end may be tapered to loosely contact said ball. The aft end of socket 585 may be externally threaded to mate with internally threaded insert 590, which may be rigidly attached to arrow shaft 510. Initial positioning of blades 540 relative to the arrow shaft may be controlled by alignment disk 520.

Broadhead arrowhead 500 may be designed such that nose tip 530, blades 540, and ball 560 may form a broadhead arrowhead whose center of gravity may be adjusted to coincide with the geometric center of ball 560. The ball may be loosely captured in position against spherically concave socket 580 which may mate with the ball to form a ball-and-socket joint. This joint may allow the broadhead arrowhead to pivot freely with respect to arrow shaft 510 and weathercock into the relative wind during flight. During the drawing of the arrow in the bow, the initial position of the broadhead unit relative to arrow shaft 510 may be held fixed and in axial alignment by means of alignment disk 520. As the bow string is released and the arrow begins to accelerate, the relative wind may push against the alignment disk, causing the broadhead blades to decouple from the disk and self-align with the oncoming air flow. Relative motion between the arrow and the alignment disk may allow the arrow to pass completely through the alignment disk, and the alignment disk then may fall to the ground close to the bow. The center of pressure of the broadhead arrowhead, being aft of the center of gravity, may cause the broadhead arrowhead to remain aligned with the relative wind throughout the flight of the arrow, thus reducing or eliminating the need for fletching. Embodiments of the present disclosure may utilize commercially available arrow shafts and shaft inserts. Conventional metals and plastics can be utilized for each component, and machining practices such as lathe work, milling, and injection molding can be incorporated in manufacturing a weathercocking arrowhead according to embodiments of the present disclosure.

Smoothbore Shotgun Slug

Embodiments of the present disclosure may improve on both the accuracy and lethality of conventional smoothbore shotgun slug designs while retaining the inherent flexibility and lower cost advantages inherent in the smoothbore shotgun. Embodiments of the present disclosure may include a forward-located obturating gas seal surrounding the slug body which may eliminate the requirement for a sealing wad between the propellant and the slug, and may allow the portion of the slug body aft of the obturator to extend into the propellant bed. Propellant gases may act upon the entire slug body aft of the obturating seal to both propel the slug down the bore and to counteract set back forces generated on the slug body due to the inertia of the interior payload. The forward located obturator seal also may allow for increased length of the slug, which in turn may allow for increased static margin of the slug via forward shifting of the center of gravity, and rearward shifting of the center of pressure. Multiple fins at the rear of the slug body may aid in shifting the center of pressure aft while allowing room within the propellant bed for both ignition between the primer and the propellant, and subsequent flame propagation throughout the propellant bed. The increased length of the slug body also may allow for a multitude of payload configurations to be incorporated within the aerodynamic body outline, which may allow tailoring of the slug to meet specific practice, hunting, self-protection, military, or law-enforcement objectives.

FIG. 11 depicts a front perspective view taken from the user's right side of slug 300 that may be launched from a smoothbore shotgun barrel constructed in accordance with embodiments of the present disclosure. The body of slug 300 may be composed of nose cap 305 attached to forward bulkhead section 312 which may support pliable obturator ring 310. Aft body 315 of slug 300 may be integrally connected to finset 320; however, there may be embodiments of the present disclosure where aft body and finset may not be integrally connected. Finset 320 may be composed of at least three fins, and each fin may have a rounded leading edge 326, a compression bevel 324, and an expansion face 322, and each fin may be canted with respected to the axis of symmetry of slug 300. The body of slug 300 may be made from plastic such as styrene, urethane, or polyester, for example, using standard plastic molding or 3D printing technology. The body of slug 300 may be manufactured as an assembly of parts wherein nose cap 305 may be separately produced from integrally produced forward bulkhead 312, aft body 315, and finset 320, or in some embodiments of the present disclosure, longitudinal sections or the entire body of the slug can be produced as an integral unit.

FIG. 12 depicts a side view of slug body 300 (FIG. 11) shown as a component in a side section view of cylindrical shotgun shell 330 in an assembled state. Circumferentially attached pliable obturator ring 310 may be tightly compressed against the inner sidewall of shell 330 which may seal against propellant gas pressure generated in propellant compartment 332. Flame propagation from primer 336 to propellant compartment 332 may be enabled via flame channel opening 333 in the base of finset 320. Obturator ring 310, aft body 315, and finset 320 may be in contact with the propellant in propellant compartment 332 and may be acted upon by the pressure generated by the burning propellant. Frangible card wad seal 334 positioned over nose cap 305 may be stabilized by granular plastic buffer material stored within buffer compartment 335 and held in position by roll crimp 338 at the forward end of the shell.

FIG. 13 depicts a side section view of slug body 300 showing one embodiment of the present disclosure containing attached nose cap 310 and high density metal sphere 340 in a forward cavity separated by integral interior bulkhead 347 from an aft cavity containing one or more pellets 345 that may be formed of metal.

FIG. 14 depicts a side section view of slug body 300 showing another embodiment of the present disclosure having a fully integral body and containing high-density combined cylindrical-conical body 342 in a forward cavity separated by integral interior bulkhead 347 from an aft cavity containing one or more pellets 345 that may be formed of metal.

FIG. 15 depicts a side section view of slug body 300 showing another embodiment of the present disclosure having a fully integral body and containing high-density combined spherical-cylindrical-conical body in a single forward cavity.

FIG. 16 depicts a front perspective view of slug body 301 showing another embodiment of the present disclosure where obturator ring 310 (FIG. 1) (which may be pliable) has been replaced with a pliable, fully split obturator seal composed of right half 350 a and left half 350 b. Interface 351, which may split the obturator seal into two identical halves, may be rotationally symmetric about the axis of symmetry of slug body 301.

FIG. 17 depicts a side section view of slug body 301 showing right half 350 a and left half 350 b of the fully split obturator seal with ramped interface 352 between the obturator seal and slug body 301. Interface 352 may include vertical gap 353 between the obturator seal and slug body 301. The obturator seal may be comprised of rearward facing cutout 355 and forward facing chamfer 357 and outer wall 360 which may interface with the inner wall of shell 330 (FIG. 2). Slug body 301 may contain one or more high density metal pellets 346 in a forward cavity with forward opening 358, separated by interior bulkhead 347, which may or may not be integral, from an aft cavity containing one or more smaller metal pellets 345.

Slug 300 (FIG. 1), which may be used in a smoothbore shotgun, may be conventionally loaded into primed shotgun shell 330 (FIG. 2) by placing a quantity of propellant into the base of the shell. Obturator ring 310 may be placed onto the body of the slug and positioned just aft of forward bulkhead 312. Slug 300 may then be inserted into the shell until (inset 320 may rest on the interior base of the shotgun shell. A granular plastic buffer may then be placed on top of nose cap 305 to fill the volume between the slug body and the shotgun shell ahead of the forward bulkhead; however, the buffer may be comprised of other materials without departing from the present disclosure. A card wad may then be placed on top of the buffer and the shotgun shell may then be crimped. Firing of the loaded shotgun shell may then be conducted as known to one of ordinary skill in the art. When slug 300 reaches free-flight, it may begin to roll about its longitudinal axis, which may decrease dispersion due to roll-averaging asymmetric forces acting upon the slug. At impact, for a slug equipped with dual penetrator mechanisms, such as shown in FIG. 4, forward penetrator 342 may decrease in velocity allowing rear pellets 345 to overtake the forward penetrator and disperse radially within the wound cavity.

Manufacturing of slug body 300 (FIG. 1) and its variations (FIG. 3, FIG. 4, and FIG. 5) and slug body 301 (FIG. 6) can be accomplished via fused filament fabrication (FFF) in embodiments of the present disclosure. The lethal sub-munition components (340, 342, 344, 345, and 346) can be inserted during the FFF manufacturing process, and the slug body may be completed with an integral nose cap, or the slug can be fabricated with separate nose cap 310 and assembly of the lethal sub-munition components can be accomplished after the slug body fabrication is completed. Other methods of fabrication, which may include but are not limited to selective laser sintering, stereo lithography, or conventional injection molding processes, can also be utilized to manufacture the slug body in embodiments of the present disclosure.

Quick-Detachable Multi-Purpose Accessory Mounting Platform

Accessories including but not limited to flashlights and spotlights may be mounted in parallel with the barrel of the firearm and can be brought into action while the firearm is in the mounted position. Such accessories may be helpful for identifying and selecting game in the field under low-light or no-light conditions. Utilization of these illuminating devices may be known to one of ordinary skill in the art. However, reasons for mounting a remote transmitter on the firearm within easy reach of the operator may be more complex. It is common practice for a hunter, when using a remote transmitter for dog behavior correction, to carry the transmitter either in a holster attached to a belt around the waist, on a lanyard around the hunter's neck or wrist, in a shoulder sling, or even in his/her pants-pocket. None of these conventional carry positions for a transmitter are conducive to applying a corrective stimulus to the dog when the hunter is in the act of aiming and firing the firearm. The situation can become particularly dangerous to a hunting party if correction to unruly dog behavior is ill-timed when applied, or is not able to be applied at all. These issues can occur due to the transmitter not being within easy reach of the hunter.

A typical scenario may involve hunting with a young or unfamiliar dog on-leash that has not been completely trained to stay in the “heel” or “sit” position as the gun is mounted and fired. Many times, an unsteady dog will break enthusiastically in this situation, and may therefore unexpectedly jerk the hunter to the point of falling, which can cause the firearm to accidentally discharge with potentially disastrous consequences. In this case, the timing of the correction should be applied when the dog is in the act of breaking. If the dog reaches a point of several feet away from the hunter before being corrected, then the dog typically does not correlate the applied corrective stimulus to the act of breaking. Furthermore, if the dog continues to repeatedly break at the sight and sound of gunfire without being properly corrected, an unintentional breaking behavior is learned that becomes extremely difficult to correct as the dog matures and the habit fully forms. Therefore, this dangerous behavior may continue to reappear unexpectedly throughout the lifetime of the dog.

Another scenario where timing of the correcting stimulus being applied may be critical can occur when a dog nears unexpected danger in the field, such as when encountering a poisonous snake. A dog without proper training may be overly curious and approach within striking distance of the snake. In this situation, a properly timed correction given by the hunter can save the dog's life. The preceding examples are only some of many possible scenarios where a corrective stimulus applied at the proper time to the dog via a remote transmitter can prevent an emergency situation from occurring. In all cases, having the transmitter easily available and close at hand may aid in correctly timing the application of the corrective stimulus.

At least one upper tie down hole 385 and lower tie down post 350 (FIG. 23) may provide a means for supplemental restraint of the accessory via elastic cords or non-stretch cords. Tie down may be accomplished by lacing a cord (i.e., one cord per mounting pad) through the one or more holes and looping the cord around the one or more posts. An interior embedded channel including recess 390 may be attached to embedded cable slot 397 and terminated by second recess 395 in an embodiment of the present disclosure. The embedded channel may contain the cord ends and loops interior to the platform. The one or more holes and posts, and the channel may be symmetrically arranged on opposing sides of the platform without departing from the present disclosure.

Platform assembly 200 may be installed on a single barrel firearm by first detaching the fore-end mounted sling, if present, and then inserting the firearm's muzzle from the rear of the platform forward through barrel clamp halves 235. The rear section of the platform may partially extend over but not contact the fore-end of the firearm, thus allowing free motion of a sliding fore-end such as when the device may be employed on a pump-action firearm. The sling may then be reattached to the fore-end through portal 280 (FIG. 21B). Once in position, one or more thumb screws 205 may be tightened, causing the barrel clamp halves and ventilated rib clamp halves 240 to apply pressure to the firearm. If a ventilated rib is present on the firearm, the ventilated rib clamp halves may contact that portion of the firearm, followed by line contact between the halves of bearing surfaces 245 (FIG. 19), and then by contact between the barrel clamp halves and the barrel. Elongated holes 255 (FIG. 20A) through the mounting platform may provide clearance and ensure that the one or more thumb screws do not bind as the clamp halves may be drawn together. Once mounted, the platform may provide multiple secure attachment pads 220, and mounting surfaces 250 for accessories which may be temporarily secured to the mounting platform with hook and loop style fasteners attached to both the accessory and the mounting pads or flats. Alternatively or additionally, hook and loop style straps can be inserted into slots 260 and 270, and the straps may be adjusted for best fit by sliding along the slots. Shelf 225 may provide a pivot point for initial alignment of the accessory during the mounting process, and also may serve as a base for supporting the accessory while it is mounted on the platform. When hook and loop fasteners may be employed on the mounting pads, the body of the mounted accessory may be raised from the surface due to the thickness of the fastener. In this case, the accessory can be positioned over the shelf closer to the hunter; while in this position, the accessory may rest on the shelf flat and can utilize the shelf flat for increased stability.

Accessories which may be mounted on mounting pads 220 may be located close to the hunter's hand holding the fore-end of the firearm. The index finger or thumb of the hunter's hand can be extended to operate the accessories with little effort, and without disrupting the mounting or operation of the gun during the act of firing. Additionally, when the hunter is seated and holding the firearm such that it is located between the hunter's legs and oriented with its butt end on the ground and the muzzle pointing up (such as may be the case when game are approaching), the mounted accessories, such as a remote transmitter, may easily be reached and operated by either hand.

While embodiments of the present disclosure may utilize thumb screws, it should be appreciated that other fastening mechanisms may be utilized without departing from the present disclosure. FIG. 30 depicts a front view of a platform according to an embodiment of the present disclosure incorporating four disc-shaped magnets 391 in place of thumb screws, and FIG. 31 depicts a side view of a platform according to an embodiment of the present disclosure showing the four disc-shaped magnets 391 in position.

Glock Magazine Release Button Removal Tool

Embodiments of the present disclosure may provide a tool which may be used on a Glock pistol to manipulate the free end of the magazine release button spring into and out of a slot in the magazine release button and therefore allow for the removal and installation of the magazine release button without damaging the interior of the magazine well. Tool 100 depicted in FIG. 25 may include several features which may aid in the removal and installation process. Wide blade 101 may move the spring to the side of the slot in the magazine release button. Hook 102 (FIG. 26), which may or may not be integral, at the end of the blade may be positioned under the spring to withdraw the free end of the spring through the opening in the slot and away from the button. Cavity 103 may be located on the face of the blade and may guide the released end of the spring away from the magazine release button in a direction opposite the line of fire and may allow the button to be transversely withdrawn from the frame and either replaced or reinstalled in a reverse orientation. Groove 104 may be located opposite the hook and may be used to guide the spring transversely and also may allow for pushing the spring back into position through the opening and into the slot of the magazine release button. Handle 105 may be on the opposite end of the tool from the blade end and may be used to aid in axial rotation of the tool as the hook is initially inserted under the spring in an embodiment of the present disclosure.

A variation of tool 101 conducive to an alternate manufacturing method wherein the head of the tool may allow for transverse camming of the free end of the spring is presented as item 150 (FIG. 27). The body of the tool also may serve as handle 151, and the handle may be of a different cross-sectional shape than the body of the tool in some embodiments of the present disclosure. The tool may use elongated head 152 (FIG. 28) to act as a camming lever between the cavity sidewall and the free end of the spring in an embodiment of the present disclosure. Right-angle extension 153 in the elongated head of the tool may allow for engagement with the free end of the spring and may allow the spring to be lifted away from the magazine release button so that disengagement may occur between the spring and the magazine release button. With no less functionality but dependent on manufacturing method, the right angle extension feature may be replaced with a notch which may engage the spring and result in the same spring-lifting capability in an embodiment of the present disclosure. Spoon-shaped cavity 154 (FIG. 29) at the opposing end of the tool from the elongated head may be used to lift the spring away from the magazine release button, allowing for removal and re-installation of the replacement button. Chamfer 155 (FIG. 29) on the side of the body opposite the cavity may allow for easier lifting of the spring end away from the cavity. Notched blade 156 may allow for re-seating of the free end of the spring into the slot of the magazine release button and may allow for pressure to be applied to the spring to push the free end through the opening and into the slot of the magazine release button in an embodiment of the present disclosure.
